New Rochelle Issues Bid for Drainage Improvements on Ashland Street and East Place

NEW ROCHELLE, NY (September 15, 2025) — The city opened bidding for drainage improvements at Ashland Street and East Place last month.

Bid number 5816 was published on August 22. The closing date is September 17,

A pre-submission conference call was held for Monday, September 8, 2025. An addendum and Q&A have both been posted.

Summary

The City of New Rochelle is seeking proposals from professional engineering firms for drainage improvements at Ashland Street and East Place, under DPW Project #24-012 and Specification #5816. The project involves designing stormwater management systems using hydrologic and hydraulic analyses to address recurring flooding near Ashland Street, East Place, Chatsworth Place, and Crestview Street, with the goal of developing bid documents for construction.

A Notice of Award is anticipated on or before September 24, 2025.

The background notes that the area west of City Park/Fifth Avenue has experienced flooding from severe storms, with a Watershed Analysis Report identifying existing drainage infrastructure as the cause and recommending improvements, included as Attachment E. Conceptual solutions must be verified or modified to convey runoff from events up to a 25-year storm, minimizing flooding at the specified locations and neighboring intersections. The city intends to publicly bid the construction contract for the recommended improvements.

The scope of work is divided into three phases.

Phase 001 involves analysis and development of conceptual solutions, including due diligence such as utility markouts, site and topographic surveys, TV inspection and cleaning, and hydrologic and hydraulic modeling. Flood mitigation benefits must be computed for 10-, 25-, 50-, and 100-year storms, limited to exterior improvements like reconfiguring drain pipes, catch basins, and manholes, excluding private property.

Deliverables include a drainage report with hydraulic analysis and quantification of benefits, plus a summary of recommendations with plans, cost estimates, and flood depth maps. Consultants must propose a lump sum fee for this phase, inclusive of reimbursables and sub-consultant fees, with completion by November 14, 2025, and a 50% progress set by October 17, 2025.

Phase 002 advances design and bid documents for the selected concept from Phase 001, focusing on flood mitigation within determined limits and excluding private property, with proposed billing rates by staff title submitted initially; a detailed proposal will be requested later, subject to negotiation. Deliverables, fee, and schedule are to be determined.

Phase 003 provides engineering support during construction on a time-and-materials basis, with a not-to-exceed estimate set after Phase 002, using the same billing rates; services include submittal reviews, milestone inspections, and technical support, with deliverables, fee, and schedule to be determined.
